Penetrating the Mask: the Gravitational Torque of Bars


The Hubble classification scheme of galaxies is based on blue-light appearance. Atlases reveal the rich variety of responses of the Population I component ('the mask') of gas and dust to the underlying , older, stellar population. However, the Population I component may only constitute 5 percent of the dynamical mass of the galaxy; furthermore , dusty masks… (More)
